Description
Technical field
It the utility model is related to a kind of anti-dumping switch, and in particular to a kind of anti-dumping switch for electrical equipment.
Background technology
For electrical equipment or Gas appliance, such as warmer, electric fan, electric heating installation using oil as medium, if placed unreasonable or artificial thin
Suddenly so that above-mentioned electrical equipment or Gas appliance can cause improper operating after tilting, such as electrical short-circuit, Gas appliance combustion instability
Deng resulting even in fire or threat to life property.To prevent these harm, generally installed on electrical equipment or Gas appliance
Anti-dumping switch.
Current anti-dumping switch is mostly such as Patent No. ZL201020612705.6 (notification number CN201898083U)
Utility model patent disclosed in《A kind of anti-dumping switch》It is shown, including plastic casing, housing includes two cavitys, wherein one
Have in individual cavity one can freely movable heavy ball, accommodate a microswitch in second cavity, separately there is a lever to be articulated with shell
In vivo；The upper surface of lever abuts heavy ball, and lower surface compresses the button of microswitch, and heavy ball can pass through because of pressure caused by gravity
Lever presses the button of microswitch, so as to cause the break-make of microswitch.
But the problem of above-mentioned patent is present has, for lever because being wholely set, heavy ball will be with the inconsistent need in lever one end
The amplitude to be rotated is fixed, and therefore, electrical equipment, which only tilts certain amplitude, could start tilt switch.Different electrical equipment exist
Inclined angle is different under different environment, for example, for the larger electrical equipment of volume may tilt less angle may result in it is non-
Run well, and may tilt larger angle for the electrical equipment of small volume and can just cause improper operating.Therefore, topple over out
Easily there is the phenomenon of failure in pass, and then causes the switch use range of this structure limited, it is impossible to suitable for all electrical equipment.
In addition, the pin joint of lever to the distance between microswitch contact point, pin joint to heavy ball contact point it
Between distance need careful design to calculate, processing and fabricating is not easy, and otherwise easily causes maloperation or operation failure, reliability is low.
Utility model content
Technical problem to be solved in the utility model is the present situation for prior art, there is provided a kind of high electricity of reliability
Device anti-dumping switch.
Technical scheme is used by the utility model solves above-mentioned technical problem：A kind of anti-dumping switch for electrical appliance, including
Support and the microswitch being installed on support, it is characterised in that：Also include the sleeve on support, be provided with the sleeve
Can relative sleeve axial movement under external force push rod, the position-limit mechanism of spring and spacing push rod shift motion, it is described
Sleeve one end is blind end, and the other end is openend, and the push rod is provided with located at microswitch side and the push rod can
Contacted with microswitch so that the flange that circuit is connected, the blind end of the spring one end and sleeve offsets, the other end with it is convex
Edge upper surface is offseted, and described push rod one end is inserted in spring, and the other end extends openend to bear external force.
As a further improvement, the microswitch is provided with binding post and can coordinated with flange with control circuit
The button of break-make, the housing of the binding post through electrical equipment are connected with external power source.When push rod is pressed by external force effect spring
During contracting, flange and button contacts, circuit turn-on, electrical equipment normal work；When electrical equipment is toppled over, the external force effect suffered by push rod disappears
Losing, push rod drives flange to move axially, flange is separated with button under the action of the spring, and circuit disconnects, and electrical equipment is stopped,
Ensure that electrical equipment is safe to use.
Improve again, jack is offered on the sleeve perisporium, the button is inserted in jack to be coordinated to control with flange
Connecting and disconnecting of the circuit.Button and Hp contacts are made by jack, make circuit communication.
Improve again, spacing in order to be carried out to the shift motion of push rod, anti-throw-out lever passes sleeve under the force of a spring,
Cause switch failure, the position-limit mechanism includes axially being opened in the bar hole on sleeve perisporium and the guiding on flange
Pin, the guide finger are inserted in bar hole and can relative bar hole axial slips.
Improve again, the guide finger there are two, and corresponding, the bar hole there are two, passes through the guiding of two guide fingers
Effect, is further ensured that push rod moves along fixation locus in sleeve, and anti-throw-out lever rocks in movement, causes flange and button
Loose contact.
Improve again, the support is a cover plate, and the microswitch is installed on cover plate lower end；And the sleeve passes through cover plate
It is divided into upper and lower two parts, the blind end of the sleeve is located at top, and the openend of the sleeve is located at bottom, push rod is existed
Coordinate control circuit break-make with flange during axial movement, it is reasonable in design.
Compared with prior art, the advantages of the utility model：The utility model by the axial movement of push rod make flange with
The break-make of snap fit control circuit, one carrys out push rod and the flange on push rod is easily worked making, as long as two carry out electrical equipment and incline
Less angle, the external force that push rod end is subject to will reduce or disappear, so that circuit disconnects, reliability is high.
